* win/configure:

	* win/configure.in: Generate error when attempting
	to build under Cygwin. The Cygwin port of Tcl/Tk
	does not build and people are filing bug reports
	under the mistaken impression that someone is
	actually maintaining the Cygwin port. A post to
 	comp.lang.tcl asking someone to volunteer as an
	area maintainer has generated no results.
	Closing bugs 680840, 630199, and 634772 and
	marking as "Won't fix".
